This position in Sargent & Lundy's Consulting group will require you to focus on our utility planning and advisory projects, such as the following:

• Preparing new generator interconnection applications, including development of conceptual single line diagram, verification of compliance with reactive power requirements, and development of steady-state, dynamic, and short circuit models to support the applications
• Reviewing ISO feasibility and system impact studies to provide guidance to our clients, who are ISO Interconnection Customers
• Performing independent power system studies, including thermal and voltage contingency, transient stability, and short circuit analyses, to support our client's generator interconnection planning strategies
• Performing advanced grid system studies to evaluate specific scenarios and impacts as required by our clients, for new conventional and renewable generation projects.

We do not sponsor employees for work authorization in the U.S. for this position.

This position requires a BS or MS in Electrical Engineering with strong academic background and coursework emphasis in Power Systems Analysis.

3+ years previous power systems engineering experience, including one or more of the following:

• Knowledge of power regions and ISOs/RTOs - PJM, MISO, NYISO, ERCOT, SPP, CAISO, and ISO-NE
• Experience in modeling inverter-based resources and renewable generation, such as Wind Turbine Generators (WTG), photovoltaic (PV), Battery Energy Storage Systems (BESS), and hybrid generation, and associated collector system for interconnection applications within software programs PSS/E, PSLF, and/or PSCAD
• Experience in using transmission planning software, particularly PSS/E, PSLF and TARA, for load flow modeling and contingency studies
• Experience in dynamic transient, stability, and other advance studies in TSAT, EMTP-RV or PSCAD is a plus.

Also extremely important are:

• Excellent verbal/written communication skills.
• Experience in writing technical reports and proposals.
• Solid interpersonal skills and ability to work with and guide others.
• Project planning and leadership skills.

In this role, we expect people to be willing or able to lead others who use modern tools:

• You are expected to lead others in taking engineering problems from issue to solution by setting expectations for using data and modern tools such as automation and AI to improve workflows, reduce rework, and deliver cost-effective designs.
• Leaders in these roles often direct automation and process-improvement work, for example, how teams automate calculations, summarize technical documents, or generate design documentation and guiding when and how AI or agentic AI tools are used while ensuring results are checked.
• Overseeing engineers who program or script (e.g., Python, MATLAB, advanced Excel) to automate engineering tasks, with review of automated outputs, is valued but not required.
• We also value additional learning, such as a minor, certificate, or other experience in Computer Science, Artificial Intelligence, Software Engineering, or related fields that enables effective oversight of automation and agentic AI-enabled engineering workflows.
